Good-Win Racing Mazda Performance Parts

Miata MX5 2006-2015 · 2.5 Liter Engine Conversions


Good-Win Racing has long specialized in 2.5 conversions for the NC Generation Miata.  We raced and set track records in the first serious 2.5 liter fully caged NC (Project NC LIGHT detailed in our forum) and later developed our dual purpose street/autocross/track "Project Blue" shown above..  The reason to use the 2.5 is easy to understand, it's a bigger Mazda factory motor that is easily installed into the NC Generation Miata for a reliable normally aspirated 200 hp Miata when trimmed with all our 2.5 goodies below.   Or add boost and make 300 HP and more! Our Project BLUE shown above with our big 1.8 Inch Header and a custom built 2.5 liter running on E85 and making over 220 hp at the wheels!  We do these installs here...and we sell you the parts below to help YOU get the most from your 2.5 conversions.

REVIEWS

I absolutely love my Roadster Sport headers, mid pipe and Q muffler. I have owned a lot of cars over the years and the quality of your product is truly exceptional. The ability to tune the Super Q is very much appreciated.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.
